Hi,
I have more than 10 years of experience working with Lisp, VLisp, VBA, AutoCAD .Net API. If you don't have any constraint of MAC then I will implement it using AutoCAD .Net API.
I have implemented project on freelancer itself : https://www.freelancer.com/projects/NET-Website-Design/AutoCAD-ObjectARX-AutoCAD-NET-Web/
I have done AutoCAD .Net API training from Autodesk Bangalore, and am not only expert with AutoCAD but also with 3D modelling software like inventor, solidworks, unigraphics.
Please let me know if you have any clarification. I would love to hear more on the project.
Looking forward to your reply.
Thanks & regards,
Sandeep Banerjee
